Hospitals now depend on connected medical devices to monitor patients and support treatment. These devices share clinical information through hospital networks and cloud platforms. They also connect with mobile applications and electronic health records. Still, if a security breach happens, it can change how these devices work and endanger safety.
The concern is growing as healthcare cyberattacks continue. In the first half of 2026, 397 large healthcare data breaches were reported to HHS OCR. These incidents affected 33.77 million individuals, with more than two breaches reported each day.
So what can healthcare organizations do to improve IoMT cybersecurity without interrupting treatment? This guide looks at the major threats and practical security measures that can help protect connected medical devices.
What Is IoMT Cybersecurity?
IoMT cybersecurity refers to the security technologies, processes, monitoring practices, and risk management methods used to protect connected medical devices. It helps prevent unauthorized access, data theft, device manipulation, and service disruptions that could affect patient care. Protection covers both medical equipment and the systems supporting its operation.
This includes device firmware, embedded software, network communications, gateways, applications, APIs, cloud platforms, vendor connections, and software dependencies.
Unlike traditional IT security, which focuses on 3 main principles, IoMT cybersecurity must address four:
Why IoMT Cybersecurity Matters for Healthcare
A cyberattack on hospital technology can affect how quickly patients receive care and whether medical equipment works as intended. For healthcare organisations, IoMT cybersecurity matters because the consequences can extend beyond financial losses or exposed records.
Patient Safety
Some medical devices continuously measure a patient's condition. Others control equipment used during treatment. If an attacker changes device settings or interferes with measurements, healthcare professionals may receive incorrect information or the equipment may behave unexpectedly.
Clinical Availability
A hospital can lose access to essential medical services even when the devices themselves have not been attacked.
Ransomware affecting a hospital network may prevent imaging systems from sending results to clinicians. If authentication services or medical device gateways stop working, staff may struggle to access the applications they need.
Such disruptions can delay examinations and treatment decisions. Hospitals must therefore consider how long clinical services can continue when supporting technology becomes unavailable.
Data Integrity and Patient Information
Stealing patient information and changing clinical data can lead to different consequences.
A data breach may expose electronic protected health information (ePHI). Altered medical readings or corrupted patient records can affect the decisions clinicians make during treatment.
Hospital Network Security
An inadequately protected medical device may give attackers access to other hospital systems.
Once inside a network, attackers may attempt to steal credentials or identify additional vulnerable systems. They could also establish persistent access and move between connected networks.
This makes cyber risks relevant to the entire hospital. Biomedical engineering teams and IT security departments need to coordinate their responsibilities rather than managing device protection separately.
